EGR Valve Blanking Plates Z19DTH
EGR Valve Blanking Plates - Z19DTH
The advantage by blanking the EGR inlet is that all the dirty and sticky exhaust gas no longer gets into the EGR valve which will stop the build up that creates most EGR valve problems.
Furthermore it will then stop all this muck getting into the inlet manifold and clogging the moving butterflies of the swirl flaps, because this clogging against the butterflies is what creates the majority of wear in the swirl flap linkage.
Fitting the more square EGR plate between the inlet manifold and the inlet stops a contaminated inlet manifold from feeding into the EGR valve and allowing it to gum up again.
